Specification of Letters Patent.

Patented May 8, 1917.

(Patent No. 1,162,657.) Divided and this application filed November 26, 1915. Serial No. 63,603.

To all 'whom it may concer-a:A

Be it known that I, EDMUND O. SoHwErr- ZER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Electrical Distributing Means, of which the following 'is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to electrical distributing means, and has for its objectthe provision of a distributing block in combination with a long, hollow metallic pole, the block being arranged to be inserted into the upper end ofthe pole to form a plug therefor, and simultaneously to act as a means for connecting the overhead conductors, and for enabling any of the overhead conductors to be connected with conductors contained within the interior of the pole.

This application 'is a division of my copending application Serial No. 7 39,624, led January 2, 1913, which has resulted in Patent Number 1,162,657, dated November 30, 1915. The present application relates particularly to the hollow transformer pole and the combined plug and terminal 4block for the overhead conductors.

Generally the device consists in a substantially cylindrical plug adapted to have a portion of its `length inserted .in the upper end of the hollow pole. A number of conductors are provided extending from the lower end of the plug, that is from the interior of the pole, to the upper end of the plug or to a portion of the plug which is disposed without the pole. Suitable binding posts or connectors are provided at both ends of the above mentioned conductors, so that connection with other conductors is made possible.

These and other features of my invention will be more clearly set forth in the accompanying detailed description, wherein reference is made to the accompanying drawings, in which*- Figure 1 is an elevational view of -a pole embodying the features of my invention.

Fig. 2 is a vertical cross-sectional view of the same taken along the line 2-2 of Fig. 1, looking in the direction indicated by the Fig. 3 is a horizontal sectional view of a portion of the hood extending over the upper end of the pole, showing in detail the method of securing the same to the pole. This view is taken along the line 3 3 of Fig. 2, looking in the direction indicated by the arrow.

Fig. 4 is an enlarged side elevational view of the combined plug and distributing terminal, and

Fig. 5 is a top View of Fig. 4, a portion of the plug being broken away to more clearly illustrate one of the connecting plates.

Similar characters refer to similar parts throughout the several views.

Referring first to Fig. 1, I have illustrated the hollow metallic pole at 6, which, as illustrated, is composed of several sections, adjacent sections being secured together by means of connectors, as more clearly illustrated in Fig. 2.A The lower section of the pole is provided with a door 7 which, when removed, provides access to the interior of the pole. As'illustrated in Fig. 2, the lowermost section of the pole contains a transformer chamber 8, which contains a water-tight ioor 9. Upon this ioor is mounted an alternating current transformer 10, which is completely surrounded by an insulating oil 11. This oil extends upwardly as illustrated to a portion of the pole immediately adjacent the door, and serves, in addition to acting as an insulator, as a means for effectively transferring the heat from the transformer to the pole'and thence to the outside air.

In the drawings I have illustrated the primary conductor for the transformer at 12, entering the pole from the bottom. This primary conductor extends upwardly through the transformer chamber to a. fuse block 13 provided immediately adjacent the doorway. From the fuse block it runs to the primary winding of the transformer 10. The secondary winding of the transformer is connected by means of a conductor 14 with the selected conductors of the terminal block of my invention.

This terminal block consists in a body portion 15 which is constructed of insulating material, such as fiber. The lower end of this plug is cylindrical, as illustrated at 16, and is provided with a flange 17 which, when the cylindrical portion 16 is inserted into the upper end of the top section of the pole, abuts against the upper edge of the section and prevents the plug from moving downwardly into the pole beyond the depth of the cylindrical portion 16. Extending longitu.

dinally within the body portion of the distributing block is a. plurality of conductor rods, 18, 19. and 20, which are -insulated from each other and which carry at their lower ends, suitable nuts and washers to facilitate the connection of the secondary conductor 14 with any one of the conductor rods 18, 19 and 20. As illustrated in Fig. 4, the rod 18 extends upwardlyI to a portion of the plug which is recessed at 21. Extending into this vrecess and embracing the upper end of the conductor rod 18 is a plate 22, which after embracing the conductor, extends away therefrom in vopposite directions and is clamped at one end by a binding post 23 and isclamped at its other end by a binding post 24. These binding posts consist in a rod,25 which extends entirely through the terminal block and is provided at both ends with external threads cooperating with nuts to afford a means for forming electrical connectionsbetween .the connecting plates and the conductor rods.

The rod 19 extends upwardly to a recessed portion 26 of the terminal block which portion is disposed above the aperture 21 as illustrated in Fig. 4. .A connecting plate 27 embraces the upper end of the conductor rod 19 in a manner'similar to the connector plate 22, and `is held by binding-posts 28 and 29.

In a similar manner, the conductor `rod 20 terminates in the recess 30, provided in the terminal block below the recess 21 and is adapted to be clamped by the connector plate 31 which, in turn, is electrically connected with .the binding posts 32 and 33.

From the construction thus far described, it will be seen that if a conductor is connected with the lower end of, say, the conductor rod. 19, and it is desired to connect an overhead wire with the terminal block in a manner so as to electrically connect with only the conductor-rod 19, all that is necessary is to `connect Ethe overhead .wire with either end of one of the binding posts 28 and 29. The same applies to bothof the other connector rods. `Although I have illustrated but three of these connector rods, it will be readily understood that any number may be employed, depending upon the size and capacity of the yterminal block which it is desired to employ.

For holding the overhead conductors so as not to allow them to place a stress upon the terminal block, I provide a hood 34 which carries a number of notches 35-.35. Secured to the inner face of the hood is a ring 36 provided with apertures registering with the notches 35 as illustrated in Fig. 3. The

. ring, in turn, is riveted lto a semi-circular terminal block.

Having thus described my invention, what I claim as new and desire to secure yby Letters Patent `of the United -States is:
